[0001] Embodiments of the present disclosure relate to the field of computer technology, and particularly to a vision testing method, a head-mounted display device, and a computer-readable medium. Background Art

[0002] A head-mounted display device (such as an AR glasses) can be used to form an image in front of the eyes of a wearing user to provide a strong visual experience. With the development and popular application of many head-mounted display devices, using a head-mounted display device for vision testing has become a practical daily option. Currently, when testing the vision of a user, the commonly adopted method is to directly display an eye chart in front of the user's eyes for vision testing.

[0003] However, when using the above method for vision testing, there are often the following technical problems: directly displaying an eye chart in a head-mounted display device, since the eye chart contains a large number of test elements and they are relatively concentrated, the user is in a blurred viewing state during the monocular test process and cannot obtain the true vision test result of the user.

[0004] The above information disclosed in this background art section is only used to enhance the understanding of the background of the inventive concept, and thus, it may include information that does not form the prior art known to those of ordinary skill in the art in this country. Summary of the Invention

[0005] This summary part of the present disclosure is used to introduce the inventive concept in a brief form, and these inventive concepts will be described in detail in the following detailed implementation part. This summary part of the present disclosure is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to be used to limit the scope of the claimed technical solution.

[0006] Some embodiments of the present disclosure propose a vision testing method, a head-mounted display device, and a computer-readable medium to solve one or more of the technical problems mentioned in the above background art section.

[0007] In a first aspect, some embodiments of the present disclosure provide a vision testing method based on a head-mounted display device. The method includes: providing a diopter adjustment prompt to a target user according to the diopter of the head-mounted display device and a target diopter, where the target user is a user wearing the head-mounted display device, and the head-mounted display device includes two display screens corresponding to the user's left eye and right eye respectively; in response to determining that the diopter of the head-mounted display device corresponds to the target diopter, for each display screen in the head-mounted display device, perform the following vision testing operations: adjust a target display screen, where the target display screen is a display screen different from the display screen in the head-mounted display device; according to a preset set of vision testing information, perform a monocular vision testing operation on the target eye of the target user corresponding to the target display screen to obtain a monocular vision testing result, where the target eye corresponds to the display screen; in response to determining that the vision testing operation is completed, display the two obtained monocular vision testing results as a vision testing result on the head-mounted display device.

[0008] In a second aspect, some embodiments of the present disclosure provide a head-mounted display device, including: one or more processors; an optical display system including at least one display screen and optical elements for imaging in front of a user's eyes; a diopter adjustment mechanism for adjusting the user's diopter corresponding to the imaging in each display screen; a storage device having one or more programs stored thereon, and when the one or more programs are executed by the one or more processors, the one or more processors are caused to implement the method described in any implementation manner of the first aspect.

[0009] In a third aspect, some embodiments of the present disclosure provide a computer-readable medium having a computer program stored thereon, where the program, when executed by a processor, implements the method described in any implementation manner of the first aspect.

[0010] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: The vision test method based on a head-mounted display device according to some embodiments of the present disclosure can improve the accuracy of the user's vision test results and enhance the user's vision test experience. Specifically, the reasons for inaccurate vision test results and poor vision test experience of users are as follows: When directly presenting an eye chart in the head-mounted display device, since the eye chart contains a large number of test elements and they are relatively concentrated, the user is in a blurred viewing state during the monocular test process, and the true vision test results of the user cannot be obtained. Based on this, in some embodiments of the present disclosure, the vision test method based on a head-mounted display device first gives a diopter adjustment prompt to the target user according to the diopter of the head-mounted display device and the target diopter. Among them, the above-mentioned target user is the user wearing the above-mentioned head-mounted display device. The above-mentioned head-mounted display device includes two display screens corresponding to the user's left eye and the user's right eye. Thus, after the target user adjusts the diopter of the head-mounted display device to the corresponding target diopter, the vision test can be started. Then, in response to determining that the diopter of the above-mentioned head-mounted display device corresponds to the above-mentioned target diopter, for each display screen in the above-mentioned head-mounted display device, the following vision test operations are performed: First step, adjust the target display screen. Among them, the above-mentioned target display screen is the display screen different from the above-mentioned display screen in the above-mentioned head-mounted display device. Thus, by adjusting the target display screen, the monocular vision test of the corresponding eye of the user is performed, and the accuracy of the monocular vision test result is improved. Second step, according to the preset vision test information set, perform the monocular vision test operation on the target eye of the above-mentioned target user to obtain the monocular vision test result. Among them, the above-mentioned target eye corresponds to the above-mentioned display screen. Thus, through the vision test information in the vision test information set, the vision condition of the target eye of the target user is determined step by step, thereby avoiding the visual blur of the user caused by directly presenting the eye chart in the head-mounted display device and improving the accuracy of the monocular vision test. Finally, in response to determining that the above-mentioned vision test operation is completed, the two obtained monocular vision test results are displayed as the vision test result in the above-mentioned head-mounted display device. Thus, the target user can know the vision test result after the monocular vision test. Also, because the method of presenting a single vision test information in the vision test information set is adopted, the negative visual effects such as visual congestion and blur caused by directly presenting the entire eye chart in the head-mounted display device can be avoided, thereby improving the vision test accuracy and the user experience.

[0018] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0019] Figure 1 Flow 100 of some embodiments of a vision detection method based on a head-mounted display device according to the present disclosure is shown. The vision detection method based on the head-mounted display device includes the following steps: Step 101, perform a diopter adjustment prompt for the target user according to the diopter of the head-mounted display device and the target diopter.

[0020] In some embodiments, the execution subject of the vision detection method based on the head-mounted display device (such as the head-mounted display device) can perform a diopter adjustment prompt for the target user according to the diopter of the head-mounted display device and the target diopter. Among them, the above-mentioned target user can be the user wearing the above-mentioned head-mounted display device. The above-mentioned head-mounted display device can be a display device for the user to wear and then view imaging content. The above-mentioned head-mounted display device can be, but is not limited to, one of the following: AR glasses, MR glasses, VR glasses. The above-mentioned target diopter can be the diopter degree that the head-mounted display device needs to be adjusted to when testing the user's naked-eye vision. As an example, the above-mentioned target diopter can be 0 degree. In practice, the above-mentioned execution subject can display vision test operation prompt information in the above-mentioned head-mounted display device in response to determining that the diopter of the above-mentioned head-mounted display device is the same as the above-mentioned target diopter. The above-mentioned vision test operation prompt information can include vision test operation prompt text and a vision test operation prompt diagram. The above-mentioned vision test operation prompt diagram can be an image for prompting the user to perform a vision test operation. For example, the above-mentioned vision test operation prompt text can be "The current diopter of the device is 0, please press any key to enter the vision test". For example, the above-mentioned vision test operation prompt diagram can be a diagram showing any key in the head-mounted display device. The above-mentioned execution subject can also display diopter adjustment prompt information in the above-mentioned head-mounted display device in response to determining that the diopter of the above-mentioned head-mounted display device is different from the above-mentioned target diopter. The above-mentioned diopter adjustment prompt information can include diopter adjustment prompt text and a diopter adjustment prompt diagram. For example, the above-mentioned diopter adjustment prompt text can be "Please adjust the vision adjustment knob to 0". The above-mentioned diopter adjustment prompt diagram can be a diagram for prompting the above-mentioned target user on how to adjust the diopter. For example, the diopter adjustment prompt diagram can show a diagram of the knob for adjusting the diopter of the head-mounted display device and an adjustment direction description. The above-mentioned head-mounted display device can include two display screens corresponding to the user's left eye and the user's right eye.

[0021] Step 102, in response to determining that the diopter of the head-mounted display device corresponds to the target diopter, for each display screen in the head-mounted display device, perform the following vision test operations: Step 1021, adjust the target display screen.

[0022] In some embodiments, the above-mentioned execution entity can adjust the target display screen. Among them, the above-mentioned target display screen is a display screen different from the selected display screen in the above-mentioned head-mounted display device. In practice, the above-mentioned execution entity can determine that the diopter of the above-mentioned head-mounted display device corresponds to the above-mentioned target diopter in response to determining that the diopter of the above-mentioned head-mounted display device is the same as the above-mentioned target diopter. The above-mentioned execution entity can also determine that the diopter of the above-mentioned head-mounted display device corresponds to the above-mentioned target diopter in response to detecting a key operation after displaying the above-mentioned vision test operation prompt information and / or the above-mentioned diopter adjustment prompt information. The above-mentioned key operation can be a key operation on a device communicatively connected to the head-mounted display device. Here, the device for communicative connection can be a smart device, and keys can be configured on the smart device. It can be understood that the interaction operation modes between the user and the head-mounted display device can include, but are not limited to, at least one of the following modes: voice interaction, gesture interaction, head control interaction, touch interaction, and key interaction.

[0023] In practice, the above-mentioned execution entity can display a preset adjustment image on the above-mentioned target display screen to adjust the target display screen. For example, the above-mentioned preset adjustment image can be a pure black image. The above-mentioned execution entity can also adjust the above-mentioned target display screen by turning off the above-mentioned target display screen. For example, if the selected display screen is the display screen corresponding to the right eye of the target user in the head-mounted display device, the target display screen can be the display screen corresponding to the left eye of the target user in the head-mounted display device.

[0024] Step 1022, according to the preset vision test information set, perform a monocular vision test operation on the target eye of the target user to obtain a monocular vision test result.

[0025] In some embodiments, the above-mentioned execution entity may perform a monocular vision test operation on the target eye of the target user corresponding to the preset vision test information set, and obtain a monocular vision test result. Among them, the above-mentioned target eye corresponds to the above-mentioned display screen. The above-mentioned monocular vision test operation may be an operation preset for testing the monocular vision of a user. For example, the monocular vision test operation may be a vision test operation based on a vision chart and / or vision test elements, and the user's vision is determined according to the target user's direction selection information for the vision test elements and / or individual vision test elements in the vision chart. The above-mentioned monocular vision test result may be the vision value of the target eye of the target user. The above-mentioned vision test information set may be represented as a vision chart for display in the above-mentioned head-mounted display device. The vision test information in the above-mentioned vision test information set may be a vision test element in the vision chart. For example, the vision test element may be "E". The direction information corresponding to each vision test information in the above-mentioned vision test information set is different. The above-mentioned direction information may represent the opening direction of the corresponding vision test element "E".

[0026] In some alternative implementation manners of some embodiments, the above-mentioned execution entity may perform a monocular vision test operation on the target eye of the target user corresponding to the preset vision test information set through the following steps to obtain a monocular vision test result: First step, perform modeling in the above-mentioned head-mounted display device to obtain a three-dimensional space model. In practice, the above-mentioned execution entity may use SLAM technology to construct a three-dimensional space model.

[0027] Step 2: Determine the target point in the above three-dimensional space model as the anchor point. Among them, the distance between the target point and the position of the target user in the three-dimensional space model corresponds to the target test distance. The target point can be the point for placing the display object. The display object can be the vision test element projected for vision testing. The target point can be the point on the wall surface in the current three-dimensional space model. It can be understood that the target point can also be the position point selected by the target user himself or according to the recommended plane. For example, the user can select the target point at any position in the three-dimensional space model, and thus the information to be projected here (such as the eye chart and / or vision test element) can be displayed with the real world as the background. Another example is that the execution entity can display at least one recommended plane in the three-dimensional space model for the user to select the target point in the plane. Specifically, when the user selects the target point in the plane, he can follow the displayed guiding information to walk near the plane, click to confirm the placement, and then the information to be projected (such as the eye chart and / or vision test element) can be displayed in the three-dimensional space model. The target test distance can be the distance preset in the three-dimensional space model for separating the user and the projected display object. For example, the target test distance can be 5m. In practice, the execution entity can determine the target point in the three-dimensional space model as the anchor point in response to determining that the distance between the target point and the position of the target user in the three-dimensional space model is the target test distance.

[0028] Step 3: Generate the monocular vision test result according to the above three-dimensional space model, the preset vision test information set, and the interaction operation information of the target user with respect to the vision test information set. Among them, the interaction operation information can include the direction information selected by the user for the displayed vision test information and / or vision test element and / or display object. The direction information selected by the user for the displayed vision test information can characterize the opening direction of the vision test element and / or display object from the user's perspective. In practice, the execution entity can generate the monocular vision test result according to the direction information selected by the user and the correct direction information of the corresponding vision test information.

[0029] Optionally, the vision test information in the above vision test information set is display object information. The above display object information may be various attribute information for generating a display object. The above display object may be a vision test element for the user to identify directions. For example, the display object may be an "E" with a random direction. The above display object information may include, but is not limited to, display object size information. The display object size information may characterize the size of the display object (vision test element). The display object size information may be represented by a corresponding vision value. The above vision test information set is a display object information sequence. The above display object information sequence may be an information sequence obtained by arranging in ascending order according to each display object size information. For example, the display object information sequence may be a sequence including 13 display object information, and the display object size information sequence included in the above display object information sequence may be (0.1, 0.12, 0.15, 0.2, 0.25, 0.3, 0.4, 0.5, 0.6, 0.8, 1.0, 1.2, 1.5).

[0030] In some optional implementation manners of some embodiments, the above execution subject may generate a monocular test result according to the above three-dimensional space model, a preset vision test information set, and the interaction operation information of the above target user with the above vision test information set through the following steps: First step, select the display object information that meets the first placement condition from the above display object information sequence as the first display object information. Among them, the above first placement condition may be that the sequence ordinal corresponding to the first display object information is a preset target ordinal. As an example, the above preset target ordinal may be the median ordinal in the above display object information sequence. For example, the above display object information sequence includes 13 display object information, and the above preset target ordinal may be 7. It should be noted that the default ordinal starts counting from 1.

[0031] Second step, generate at least one first display object according to the above first display object information. Each generated first display object corresponds to direction information. In practice, the above execution subject may generate a preset number of display objects with random orientations as each first display object according to the display object size information included in the above first display object information. The direction information corresponding to the generated first display object characterizes the orientation of the first display object. For example, the direction information may be, but is not limited to, one of the following: up, down, left, right. As an example, the above preset number may be 3.

[0032] In the third step, place at least one generated first display object at the position of the above-mentioned anchor point in the above-mentioned three-dimensional space model. In practice, the above-mentioned execution entity can place each generated first display object one by one at the position of the above-mentioned anchor point in the above-mentioned three-dimensional space model. The above-mentioned placing one by one can be understood as follows: after the above-mentioned target user makes a direction selection operation on the first displayed first display object, the above-mentioned execution entity can then place the second first display object at the position of the above-mentioned anchor point until all the generated first display objects are placed. The above-mentioned direction selection operation can be that the above-mentioned target user selects the corresponding direction key or the illustration representing the direction.

[0033] In the fourth step, generate a first selection result according to the direction selection information corresponding to each first display object placed by the above-mentioned target user and the direction information corresponding to each first display object. Among them, the direction selection information can be the orientation of the first display object placed as feedback by the above-mentioned target user through an interaction operation. In practice, the above-mentioned execution entity can generate a first selection result representing the user's sequential selection result in response to determining whether the direction selection information corresponding to each first display object of the above-mentioned target user is the same as the direction information corresponding to each first display object. The above-mentioned first selection result can be a sequence representing the user's sequential selection result. The above-mentioned first selection result can include the above-mentioned preset number of single selection results. For example, the single selection result can be a Boolean type variable. When the selection result is "TRUE", it can represent that the target user has made a correct selection. When the selection result is "FALSE", it can represent that the target user has made an incorrect selection. The target user making an incorrect selection can mean that the target user has selected a direction key different from the direction information corresponding to the displayed display object or has selected a skip key. The above-mentioned skip key can be a key to skip this selection. For example, the skip key can be the confirmation key.

[0034] In the fifth step, generate a monocular vision test result according to the above-mentioned first selection result and the above-mentioned display object information sequence. In some optional implementation manners of some embodiments, the above-mentioned execution entity can generate a monocular vision test result according to the above-mentioned first selection result and the above-mentioned display object information sequence through the following steps: In the first step, in response to determining that the above-mentioned first selection result indicates that the first two selections are incorrect, execute the first determination step: The first sub-step is to select, according to the above first display object information, the display object information that meets the first order condition from the above display object information sequence as the second display object information. Among them, the above first reverse order condition may be that the sequence order of the second display object information is larger than the sequence order of the above first display object by a first preset difference. As an example, the above first preset difference may be 3. For example, the sequence order of the first display object information in the above display object information sequence may be 7, and the display object size information included may be 0.4. The sequence order of the second display object information may be 10, and the display object size information included may be 0.8. For example, when the above first selection result is (FALSE, FALSE, TRUE), it may indicate that the target user made mistakes in the first two selections.

[0035] The second sub-step is to place the generated at least one second display object at the position of the above anchor point in the above three-dimensional space model according to the selected second display object information. Among them, the second display object corresponds to direction information. In practice, first, the above execution entity may generate each of the above preset number of display objects with random orientations as each second display object according to the display object size information included in the above second display object information. Then, the above execution entity may place each of the generated second display objects one by one at the position of the above anchor point in the above three-dimensional space model.

[0036] The third sub-step is to generate a second selection result according to the direction selection information of the target user corresponding to each placed second display object and the direction information corresponding to each second display object. In practice, the above execution entity may generate a second selection result representing the user's sequential selection result in response to determining whether the direction selection information of the target user corresponding to each second display object is the same as the direction information corresponding to each second display object. The above second selection result may include the single-selection results of the above preset number. For example, the above execution entity may generate a selection result representing a selection error as a single-selection result in response to determining that the direction selection information of the target user corresponding to a single second display object is different from the direction information corresponding to the second display object. The above execution entity may also generate a selection result representing a correct selection as a single-selection result in response to determining that the direction selection information of the target user corresponding to a single second display object is the same as the direction information corresponding to the second display object.

[0037] The fourth sub-step is to execute the first determination sub-step in response to determining that the second selection result indicates that the first two selections are incorrect: Sub-step 1: According to the selected second display object information, select the display object information that meets the above first-order condition from the above display object information sequence as the third display object information. In practice, the above execution entity can select the display object information whose sequence order in the above display object information sequence is greater than the sequence order of the above second display object information by the above first preset difference as the third display object information. For example, the sequence order of the second display object information in the above display object information sequence can be 10, and the display object size information included can be 0.8. The sequence order of the third display object information can be 13, and the display object size information included can be 1.5.

[0038] Sub-step 2: Determine the visual acuity test range information according to the selected second display object information and the selected third display object information. Among them, the above visual acuity test range information can be the visual acuity range of the above target user measured. In practice, the above execution entity can determine the visual acuity values represented by the display object size information included in the above second display object information and the visual acuity values represented by the display object size information included in the above third display object information as the visual acuity test range information. For example, the display object size information included in the display object information is the visual acuity value. The display object size information included in the above second display object information is 0.8. The display object size information included in the above third display object information is 1.5. The visual acuity range represented by the determined visual acuity test range information is 0.8 to 1.5.

[0039] Sub-step 3: Place the at least one generated third display object at the position of the above anchor point in the above three-dimensional space model according to the selected third display object information. In practice, first, the above execution entity can generate each of the above preset number of display objects with random orientations according to the display object size information included in the above third display object information as each third display object. Then, the above execution entity can place each of the generated third display objects one by one at the above anchor point in the above three-dimensional space model.

[0040] Sub-step 4: Determine the third selection result according to the direction selection information of each third display object corresponding to the above target user and the direction information corresponding to each third display object. In practice, the above execution entity may generate a third selection result representing the user's sequential selection result in response to determining whether the direction selection information of each third display object corresponding to the above target user is the same as the direction information corresponding to each third display object. The above third selection result may include the above preset number of single selection results. For example, the above execution entity may generate a selection result representing a selection error as a single selection result in response to determining that the direction selection information of the above target user corresponding to a single third display object is different from the direction information corresponding to the third display object. The above execution entity may also generate a selection result representing a correct selection as a single selection result in response to determining that the direction selection information of the above target user corresponding to a single third display object is the same as the direction information corresponding to the third display object.

[0041] Sub-step 5: In response to determining that the third selection result represents that the first two selections are correct, generate a monocular vision test result according to the selected third display object information. In practice, the above execution entity may, in response to determining that the third selection result represents that the first two selections are correct, use the display object size information included in the above third display object information as the monocular vision test result to generate a monocular vision test result. For example, when the third selection result is (TRUE, TRUE, FALSE), it may represent that the first two selections are correct.

[0042] Optionally, the above execution of the first determination sub-step may further include the following steps: First step: In response to determining that the third selection result represents that there is one error in the first two selections, based on the third display object information, execute the following first loop step: First sub-step: According to the third display object information, select the display object information that meets the second reverse order condition from the above display object information sequence as the fourth display object information. Among them, the above second reverse order condition may be that the ordinal number of the selected fourth display object information in the above display object information sequence is smaller than the ordinal number of the above third display object information in the above display object information sequence by a second preset difference. As an example, the above second preset difference may be 1. For example, the ordinal number of the third display object information in the above display object information sequence may be 13, and the included display object size information may be 1.5. The sequence ordinal number of the third display object information may be 12, and the included display object size information may be 1.2.

[0043] The second sub-step is to determine the third display object information as the monocular vision test result in response to determining that the vision test result characterized by the selected fourth display object information is not within the vision range characterized by the determined vision range information. In practice, the above-mentioned execution entity may, in response to determining that the display object size information included in the selected fourth display object information is not within the numerical range (i.e., 0.8 to 1.5) characterized by the determined vision range information, use the display object size information included in the third display object information as the vision test result to generate a monocular vision test result.

[0044] The third sub-step is to perform the following steps in response to determining that the vision test result characterized by the fourth display object information is within the vision test range characterized by the above-mentioned vision test range information: Sub-step one: According to the fourth display object information, place at least one generated fourth display object at the position of the above-mentioned anchor point in the above-mentioned three-dimensional space model. In practice, first, the above-mentioned execution entity may generate each of the above-mentioned preset number of display objects with random orientations as each fourth display object according to the display object size information included in the above-mentioned fourth display object information. Then, the above-mentioned execution entity may place each of the generated fourth display objects one by one at the position of the above-mentioned anchor point in the above-mentioned three-dimensional space model.

[0045] Sub-step two: Determine the fourth selection result according to the direction selection information of the above-mentioned target user corresponding to each placed fourth display object and the direction information corresponding to each fourth display object. In practice, the above-mentioned execution entity may generate a fourth selection result representing the user's sequential selection result in response to determining whether the direction selection information of the above-mentioned target user corresponding to each placed fourth display object and the direction information corresponding to each fourth display object are the same.

In practice, the above execution entity may display the obtained two monocular visual acuity test results in the display space of the head-mounted display device. As an example, the detection result interface in the display space that displays the monocular visual acuity test result 201 corresponding to the left eye of the target user, the monocular visual acuity test result 202 corresponding to the right eye of the target user, and the operation prompt information 203 can be referred to Figure 2 .

[0096] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: The vision test method based on a head-mounted display device according to some embodiments of the present disclosure can improve the accuracy of the user's vision test results and the user's vision test experience. Specifically, the reasons for the inaccurate vision test results and poor vision test experience of users are as follows: When directly displaying an eye chart in a head-mounted display device, since the eye chart contains a large number of test elements and they are relatively concentrated, the user is in a blurred viewing state during the monocular test process and cannot obtain the true vision test results of the user. Based on this, in some embodiments of the present disclosure, for the vision test method based on a head-mounted display device, first, according to the diopter of the head-mounted display device and the target diopter, a diopter adjustment prompt is given to the target user. Among them, the above-mentioned target user is the user wearing the above-mentioned head-mounted display device. The above-mentioned head-mounted display device includes two display screens corresponding to the user's left eye and the user's right eye. Thus, after the target user adjusts the diopter of the head-mounted display device to the corresponding target diopter, the vision test can be started. Then, in response to determining that the diopter of the above-mentioned head-mounted display device corresponds to the above-mentioned target diopter, for each display screen in the above-mentioned head-mounted display device, the following vision test operations are performed: The first step is to adjust the target display screen. Among them, the above-mentioned target display screen is the display screen different from the above-mentioned display screen in the above-mentioned head-mounted display device. Thus, by adjusting the target display screen, the monocular vision test of the corresponding eye of the user is performed, and the accuracy of the monocular vision test results is improved. The second step is to perform a monocular vision test operation on the target eye of the target user according to the preset vision test information set, and obtain the monocular vision test results. Among them, the above-mentioned target eye corresponds to the above-mentioned display screen. Thus, through the vision test information in the vision test information set, the vision condition of the target eye of the target user is determined step by step, so that the visual blur caused by directly displaying the eye chart in the head-mounted display device can be avoided, and the accuracy of the monocular vision test is improved. Finally, in response to determining that the above-mentioned vision test operation is completed, the two obtained monocular vision test results are used as the vision test results and displayed in the above-mentioned head-mounted display device. Thus, the target user can obtain the vision test results after the monocular vision test. Also, because the method of presenting a single vision test information in the vision test information set is adopted, the negative visual effects such as visual congestion and blur caused by directly presenting the entire vision test chart in the head-mounted display device can be avoided, thereby improving the accuracy of the vision test and the user experience.
